BRACKET.

Specification of Letters Patent. Patented Sept. 28, 1920.

Application filed April 16, 1920. Serial No. 374,487.

To all lwhom 25 may concern Be it known that I, AUGUST P. SANDBERG, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State o1 Minnesota, have invented certain new and useful Improvements in Brackets, of which the following is a specication.

This invention relates to supporting devices and the object is to provide an improved form of bracket, especially adapted for the use of supporting window or .tlower boxes from the window sills upon the outside of the wall. Further objects will be disclosed in the course of the specification, and in the accompanying drawing, in which:

Figure 1 is a sectional view of a window box shown as held in position by my improved bracket with a `portion thereof broken away.V

Fig. 2 isan enlarged detail view of a portion of the bracket as seen when looking in the direction of the arrow in Fig. 1.

Fig. 3 is a detail sectional view on the line 3 3 in Fig. 2.

Referring to the drawing by reference numerals 4 designates a wall having a window with a sill 5 to which is hung my improved bracket consisting of a vertical portion 6.and an integrally formed horizontal portion 7. The bracket portions 6 and 7 are made preferably from semitubular sheet metal and are formed at their outer and lower ends into hooks 8 and 9, suchhooks being adapted to grasp and support a box 10 as shown in F igrl.

The means by which the bracket is secured `consists of a clamp having an upper fixed jaw 11 and a lower vertically adjustable toothed jaw 12 adapted to grasp the sill as shown. A piece of felt or other l:fabric or fibrous material 13 may be glued to the jaw 11 to prevent the upper part of the sill from becoming scratched or bruised.

The jaw 12 is made integral with a memi ber 14 which is slidably secured to the bracket by a guide 15 and which is provided with a lug ladapted to slide on the inner side of the bracket. The lug 16 is provided with a vertical Vthreaded hole in which engages a threaded bolt 17 having a thumb nut 18 at its upper end. Thus when the nut 18 is turned the clamping jaws 11 and 12 can be opened or closed to the degree desired. At the lower end of the bracket I provide an extension 19 in which is threaded a bolt 20 having a thumb nut 21 at one end and a resting plate 22 at the other end. Thus proper adjustments may be made when there is a variance in distance between the wall and the edge of the sill or where the box 10 tends to sag at one or both ends.

It is obvious thatV with a device of this .kind window boxes may be secured in place or removed in but a few minutes time and without leaving marks or holes of any description on the sill or wall. It is further obvious that when so desired the brackets may be secured to suitable supports within a house in which case a board may be placed on the horizontal extensions 7 and be used as a shelf.

What I claim is:

1. A device of the class described consisting of a bracket having means for supporting a box, a clamp atY the upper end of the bracket, means for adjusting the lower end of the bracket relative to the vertical position of the upper end.

2. A bracket adapted to be secured to the sill in a wall, consisting of a vertical portion and means for securing a box thereto, a clamp at lthe upper end of said bracket portion adapted to grip said sill, a rest plate adapted to rest against the wall. near the lower end of said bracket portion and means for adjustably securing it to said portion.

In testimony whereof I aix my si nature.

AUGUST P, SANDB RG,
